High-voltage circuit breakers are one of the important control devices in the power system. There are a large number of high-voltage circuit breakers operating in the power grid, with complex operating conditions and technical requirements. Their operational reliability not only affects the circuit breakers themselves but also impacts other equipment and even the entire power grid. Therefore, testing the dynamic characteristics of high-voltage circuit breakers is a crucial task. However, traditional methods for testing these characteristics suffer from complexities in operation and low testing accuracy. To address these issues, the High-Voltage Switch Characteristic Tester was developed.

The High-Voltage Switch Characteristic Tester is a versatile computer-based intelligent testing instrument designed for various types of high-voltage switches. It comes with a built-in high-frequency DC power supply and is suitable for testing the operational characteristics of high-voltage switches of various voltage levels, including oil-filled, vacuum, SF6, and GIS types, both domestically and internationally. It can also perform low-voltage tests and reclosing tests. Utilizing photoelectric pulse technology, microcontroller technology, and reliable anti-electromagnetic radiation technology, the tester is paired with a dependable speed/distance sensor. It features easy wiring and simple operation—only one closing (opening) action is needed to obtain all the data. The instrument can print all necessary data, including the current waveform of the breaking point and the motion curve of the moving contact, facilitating analysis and storage. It is an extremely convenient tool for maintenance and testing of high-voltage switches.
